Resistance calculation

In the following network of 12 identical resistances, calculate the equivalent resistance between points A and C

If the unknown resistance calculated without using the end correction, is R_(1) and with using the end corrections is R_(2) then (assume same end correction at both ends)

An Ac circuit with f=1000 Hz consists of a cail of 200 mH and negligible resistance. Calculate the voltage across the coil, if the effective current of 5 mA is flowing.

In the circuit shown in figure-3 .3 89, the voltmeter reads 30V when it is connected across 400 Omega resistance. Calculate what the same voltmeter will read when it is connected across the 300 Omega resistance.

State ohm's law. In the circuit shown in figure, a voltmeter reads 30 volts when it is connected across 400 ohm resistance. Calculate what the same voltmeter will read when it is connected across the 300 ohm resistance.

In the circuit given below, a voltmeter reads 20V when it is connected across 400Omega resistance. Calculate what the same voltmeter will read when connected across the 200Omega resistance.
