In how many equal parts a wire having resistance of `100Omega` be cut, so that we may obtain a resistance of `1Omega` by connecting them in parallel?

A piece of wire having resistance R is cut into four parts. How does the resistance of each part compare with the original resistance?

Show how you would connect three resistors, each of resistance 6omega, so that the combination has a resistance of : 9 omega

Show how you would connect three resistors, each of resistance 6omega, so that the combination has a resistance of : 4 omega

Two cells, E_(1) and E_(2) of emfs 4 V and 8 V having internal resistances 0.5 Omega and 1.0 Omega respectively are connected in opposition to each other. This combination is connected in opposition to with resistance of 4.5 Omega and 3.0 Omega . Another resistance of 6 Omega is connected in parallel across the 3 Omega resistor. Draw the circuit diagram

Ten identical wires each having a resistance of 1Omega are connected in parallel. The combination will have a resistance of

A silver wire has a resistance of 2.1Omega at 27.5^@C and a resistance of 2.7Omega at 100^@C . Determine the temperature coefficient of wire
