6 V.

Front

How do you calculate total resistance in a parallel circuit?

Back

Use the formula 1/R_total = 1/R1 + 1/R2 + ... + 1/Rn.

A material that allows electrons to move easily.

Front

What is resistance?

Back

The opposition to the flow of electric current, measured in ohms.

Front

What happens to the total current in a parallel circuit?

Back

The total current is the sum of the currents through each parallel branch.

Front

What is the formula for calculating voltage in a circuit?

Back

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