Electric charge:
- The property of subatomic particles that causes them to experience a force when placed in an electric and magnetic field.
- Electric charges are of two types: Positive and Negative, commonly carried by charge carriers protons and electrons.
- Quantisation of charge, q = ne, where q = charge, n = number of electron, e = electronic charge
- The SI unit of charge is Coulomb (C).
Electric current:
- It is defined as the charge per unit of time.
- Formula, current, \(i=\frac{q}{t}\), where q = charge, t = time
- The SI unit of current is Ampere (A).
Calculation:
Given,
Current, i = 2 A, time, t = 2 min = 120 s
Charge, q = it
q = 2 × 120
q = 240 C
Hence, the amount of electric charge that flows through the circuit is 240 C.
