What unit is used to measure current?

Back

Amps

Front

Which battery will light up the bulb the brightest?

Back

12 V

Front

What is the formula to calculate current in a circuit?

Back

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

Front

What unit is used to measure resistance?

Back

Ohms

Front

What is the total resistance in a series circuit?

Back

The total resistance is the sum of all individual resistances.

Front

How do you calculate the total resistance in a parallel circuit?

Back

1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

What is Ohm's Law?

Back

Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance.

Front

What happens to the current in a series circuit if one component fails?

Back

The current stops flowing in a series circuit if one component fails.

Front

What is the effect of increasing resistance on current in a circuit?

Back

Increasing resistance decreases the current, according to Ohm's Law.

Front

What is the relationship between voltage, current, and power?

Back

Power (P) = Voltage (V) * Current (I) in watts.
