Electricity for Everyone

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) in a circuit is directly proportional to the voltage (V) across it and inversely proportional to the resistance (R). It can be expressed with the formula: I = V/R.

What happens in a series circuit if one bulb goes out?

Back

In a series circuit, if one bulb goes out, the entire circuit stops working because the current has only one path to follow.

Front

What is Direct Current (DC)?

Back

Direct Current (DC) is the type of electric current that flows in only one direction, commonly used in batteries.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where components are connected across common points or junctions, allowing multiple paths for current to flow.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, and the same current flows through all components. In a parallel circuit, components are connected across the same voltage source, allowing current to split among them.

Front

What is voltage?

Back

Voltage, also known as electric potential difference, is the measure of the energy per unit charge available to drive the flow of current in a circuit.

Front

What is resistance?

Back

Resistance is a measure of the opposition to the flow of electric current in a circuit, measured in ohms (Ω).

Front

What is the unit of electric current?

Back

The unit of electric current is the ampere (A).

Front

What is the formula for calculating electrical power?

Back

Electrical power (P) can be calculated using the formula: P = V × I, where V is voltage and I is current.

Front

What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and load.
