Question

2. The 60 W incandescent lamp and the 100 W incandescent lamp are each designed to be connected to a 220 V cable. Both lamps are connected in series and the string is connected to a 220 V mains supply. Explain which bulb will glow brighter.

1. Two conductors with resistances of 10 ohm and 20 ohm are connected in series. and the circuit is connected to a voltage of 60 v. A. Determine the current flow in each conductor. B. Determine the voltage on each conductor. C.Determine the total resistance of the circuit.

3. The resistance of metal wire is 9 ohms. In how many equal parts does the wire have to be cut in order to obtain a conductor with a resistance of 1 Ohm when the cut parts are folded in parallel?

5. The total resistance of a series of conductors of several conductors of the same resistance is 144 Ohms, but if the same conductors are connected in parallel, the total resistance of the circuit is 4 Ohms. Determine the resistance of each cundoctor.
