What are series circuits Electricity for kids?
A series circuit consists of a single pathway through which electricity can flow. All of the parts of a series circuit—power source, wires, and devices—are connected along the same pathway; the devices are connected one after another, with no branches. Current moves through one device, then the next, and so on.
What is DC and AC current for kids?
Direct current (DC) is a constant flow from negative to positive, while alternating current (AC) flows in a wave pattern that vibrates at a specific hertz, meaning that it cycles from negative to positive a certain number of times per second.
What is the rule for current in a DC series circuit?
Rules for Series DC Circuits. The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of the individual resistances. The total voltage across a series circuit is equal to the sum of the individual voltage drops.
What is DC electricity kids?
Direct Current (DC) – Direct current is the constant flow of electric charge in one direction. Batteries generate direct current to power handheld items. Most electronics use direct current for internal power often converting alternating current (AC) to direct current (DC) using a transformer.
What is series and parallel circuit for kids?
In a type of electric circuit called a series circuit, all of the current flows through each part of the circuit. In a parallel circuit the current is divided into separate paths. Each wavy line represents a device, such as a lightbulb, that uses electric current.
What is DC current used for?
Direct current is used in any electronic device with a battery for a power source. It is also used to charge batteries, so rechargeable devices like laptops and cell phones come with an AC adapter that converts alternating current to direct current.
What is a DC series circuit?
When all the resistive components of a DC circuit are connected end to end to form a single path for flowing current, then the circuit is referred to as a series DC circuit. If this series combination is connected across a voltage source, the current starts flowing through that single path.
What is a DC circuits?
A Direct Current circuit is a circuit that Electric Current flows through in one direction. DC is commonly found in many low-voltage applications, especially where these are powered by Battery. Most electronic circuits require a DC power supply.
What is current ks2?
Current: this is the amount of electricity flowing through the circuit (basically a flow of electrons moving in a loop in the circuit). It can be measured using an ammeter and measured in amps. Some objects conduct electricity; this means they allow electricity to flow through them easily. These are called conductors.
What is direct current kids?
Direct current (DC or “continuous current”) is the flow of electricity in a single direction, from the positive to the negative terminals (potential, poles). The direct current always flow in the same direction, distinguishing it from the alternating current (AC).
Why is the current in a series DC Circuit the same?
In this way, the same current circulates through every resistor connected in series. Hence, it can be concluded that in a series DC circuit, the same current flows through all parts of the electrical circuit. Again according to Ohm’s law, the voltage drop across a resistor is the product of its electrical resistance and the current flow through it.
What are the laws of a DC Circuit?
DC circuits are ones powered by a voltage source that pushes current in one direction only. This lesson will use DC circuit laws including Ohm’s law, and the junction rule to analyze a circuit that requires specific currents, resistances and DC voltage source. Updated: 04/01/2021 It’s everyone’s favorite day in physics – lab day with circuits!
What are the different types of electrical circuits?
Any electrical circuit can be categorized into three different groups – series, parallel, and series-parallel. So for example, in the case of DC, the circuits can also be divided into three groups, such as series DC circuit, parallel DC circuit, and series and parallel circuit.
How are three resistors connected in a DC Circuit?
Below is a figure of a DC series circuit with three resistors. The flow of current is shown here by a moving point. Note that this is just a conceptual representation. Suppose three resistors R 1, R 2, and R 3 are connected in series across a voltage source of V (quantified as volts) as shown in the figure.
