Circuits Review

Front

What is the formula for calculating total resistance in a parallel circuit?

Back

1/R_total = 1/R1 + 1/R2 + 1/R3 + ... (where R1, R2, R3 are the resistances of individual resistors)

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 relationship between voltage and current in a parallel circuit?

Back

The voltage across each resistor in a parallel circuit is the same.

Front

How does the resistance of a parallel circuit compare to the individual resistances?

Back

The total resistance is always less than the smallest individual resistance.

Front

What is the effect of adding more resistors in parallel on the total resistance?

Back

Adding more resistors in parallel decreases the total resistance.

Front

What is the unit of resistance?

Back

Ohm (Ω)
