Answer: Rate of flow of charge.
- A Rate of flow of voltage
- B Rate of flow of charge
- C Force per unit charge
- D Charge per unit area
Correct answer: B. Rate of flow of charge
Explanation: Electric current I = dQ/dt = charge flowing per unit time. Unit: Ampere (A) = Coulomb/second.
In series, the same current flows through both resistors; in parallel, the current splits between branches and the voltage across each resistor is the same.
