Welcome to your IGCSE Physics Quiz-4
1) What is the SI unit of measurement for voltage?
2) Which of the following materials typically has the lowest electrical resistance?
3) In a series circuit, how does the total resistance change as more resistors are added?
4) The power dissipated in a circuit can be calculated using which formula?
5) What is the purpose of a diode in an electrical circuit?
6) If one resistor in a series circuit fails (opens), what happens to the current in the circuit?
7) In a parallel circuit, if one resistor fails (opens), what happens to the current in the circuit?
8) In a series circuit, how does the current passing through each resistor compare to the total current flowing through the circuit?
9) If one resistor in a parallel circuit is removed (short-circuited), what happens to the total resistance of the circuit?
10) In a parallel circuit, if one resistor has twice the resistance of another resistor, how do their current values compare?
