What to Focus On
- Electric current is the rate of flow of charge.
- Formula: I = Q/t.
- SI unit of current is ampere.
- Potential difference is work done per unit charge.
- Formula: V = W/q = F_e l/q.
- SI unit of potential difference is volt.
- Ohm's law: V is directly proportional to I at constant temperature.
- Formula: V = IR.
- SI unit of resistance is ohm.
Common Mistakes to Avoid
Electric current is the flow of electrons only, and the direction of current is the same as electron flow.
Any motion of charges in a conductor is electric current, even if it is random motion in an open circuit.
Ammeter and voltmeter can be connected anywhere in the circuit because both only measure electric quantities.
Memory Tips
Electric current as ordered motion of charges
Formula for electric current
Ammeter connection
Voltmeter connection
