Differentiate between resistances in series and parallel.
With a neat labelled diagram and derive the equation for three resistances connected in parallel.
An electric lamp of 100 Ω, a toaster of resistance 50 Ω, and a water filter of resistance 500 Ω are connected in parallel to a 220 V source. What is the resistance of an electric iron connected to the same source that takes as much current as all three appliances, and what is the current through it?
Find the current in each resistor in the circuit shown below:
A resistor of 8 ohms is connected in parallel with another resistor X. The resultant resistance of the combination is 4.8 ohms. What is the value of the resistor X?
Five resistors, each 3 Ω, are connected as shown in Fig. Calculate the resistance
- between the points P and Q.
- between the points X and Y.
How does the resistance of a metallic wire depend on the length of wire?
Calculate equivalent resistance in the following cases:
A coil in the heater consumes power P on passing current. If it is cut into halves and joined in parallel, it will consume power:
Two resistors having resistance 8 Ω and 12 Ω are connected in parallel. Find their equivalent resistance.
