When a fourth resistor is connected in series with three resistors, the total resistance
Answer: Option B
The ampere is the unit of resistance.
Ohm's law describes how current is related to voltage and resistance.
Answer: Option A
The formula for finding resistance when current and voltage are known is R = I/V.
Explanation:
Ohm's Law : V = IR
The formula for finding voltage when resistance and current are known is V = I/R.
