Current and resistance

Front

What happens to the current in a circuit as resistance increases?

Back

The current decreases.

Front

What is the formula to calculate resistance?

Back

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

Front

What are the units of current?

Back

Amperes (A)

Front

What is the relationship between charge, current, and time?

Back

Charge flow (Q) = Current (I) x Time (t)

Front

What is the unit of resistance?

Back

Ohms (Ω)

Front

If the current is 2A and the voltage is 10V, what is the resistance?

Back

5 Ω

Front

How much charge flows through a wire with a current of 5.4A in 80 seconds?

Back

432C

Front

What is Ohm's Law?

Back

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

Front

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

Back

The current increases.

Front

What is the effect of decreasing resistance on current with constant voltage?

Back

The current increases.
