Question #186Basic Electricity and Electronics
What formula is used to calculate voltage in a circuit?
- Voltage (E) equals current (I) multiplied by resistance (R) [E=I*R Ohm's Law] ✓ Correct answer
- Voltage (E) equals current (I) divided by resistance (R)
- Voltage (E) equals current (I) added to resistance (R)
- Voltage (E) equals current (I) minus resistance (R)
Explanation: Ohm’s law rearranged for voltage is E = I × R.
