Front

What resistance is needed to cause a 20A current flow because of a 100V battery?

Back

5 Ohms.

Front

Electricity that flows in a closed path is called a _________.

Back

Circuit.

Series and parallel.

Front

What is the unit of electric current?

Back

Ampere (A).

Front

What is Ohm's Law?

Back

V = I × R (Voltage = Current × Resistance).

Front

What is the unit of resistance?

Back

Ohm (Ω).

Front

What is the difference between series and parallel circuits?

Back

In series circuits, components are connected end-to-end, while in parallel circuits, components are connected across the same voltage source.

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases.
