Question

1.) voltage is a measure of *
a.) rate of current
b.) electrical pressure
c.) available energy
d.) all of these

Explanation:

Voltage, also known as electric potential difference, is often described as the "electrical pressure" that drives the flow of electric charge (current) in a circuit. The rate of current is measured by current itself (in amperes). Available energy is a more general term and not the direct measure of voltage. Since only B is correct, D (all of these) is incorrect.

Answer:

B. electrical pressure
