a current of 0.2a flows through a component with a resistance of 40 ohms. calculate the potential difference.
a current of 0.2a flows through a component with a resistance of 40 ohms. calculate the potential difference.
Answer: The potential difference across a component is given by Ohm’s law as:
V = I * R
Where:
- V is the potential difference in volts (V)
- I is the current in amperes (A)
- R is the resistance in ohms (Ω)
V = I * R
V = 0.2 A * 40 Ω
V = 8 V
Therefore, the potential difference across the component is 8 volts.
