Electrical pressure is measured in

Electrical pressure is measured in

• A. volts
• B. ohms
• C. watts
• D. amps

Answer: (A)

Electrical pressure is the potential difference that pushes charge through a circuit, and it’s measured in volts. Think of voltage as the push that moves electrons—the bigger the push, the more current can flow through a given resistance. That’s why volts are used to quantify this “pressure.” The other units describe different things: ohms measure resistance, watts measure power, and amps measure current. A quick illustration: with 9 volts across a 3-ohm resistor, the current would be about 3 amperes, showing how more voltage increases current for the same resistance.
