Front

What is the formula to calculate voltage in an electrical circuit?

Back

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

Front

What is the unit of resistance?

Back

Ohm (Ω)

Front

What is the unit of electric current?

Back

Ampere (A)

Front

What are the two types of electric circuits?

Back

Series and Parallel circuits

Front

In a series circuit, how does the current behave?

Back

The current is the same through all components.

Front

In a parallel circuit, how does the voltage behave?

Back

The voltage is the same across all components.

Front

What is the strongest part of a magnet called?

Back

The poles.

Front

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

Back

The total resistance increases.
