A moving coil galvanometer has a resistance of 60 \(\Omega\) and it indicates full deflection on passing a current of 4.5 mA. A voltmeter is made using this galvanometer and a 4.5 k\(\Omega\) resistance. The maximum voltage, that can be measured using this voltmeter, will be close to
A potentiometer wire, 10 m long, has a resistance of 40\(\Omega\). It is connected in series with a resistance box and a 4 V storage cell. If the potential gradient along the wire is 0.4 mV cm\(-\)1, the resistance unplugged in the box is
In the circuit shown, if the 10 \(\Omega\) resistor is replaced by a resistor of 15 \(\Omega\), then what is the amount of current drawn from the battery?


In the following circuit, assuming point A to be at zero potential, then what is the potential at point B?
A shunt is connected in parallel with a galvanometer. Why?
In the arrangement shown in figure, when the switch S2 is open, the galvanometer, shows no deflection for \(l\) = 50 cm when the switch S2 is closed, the galvanometer shows no deflection for \(l\) = 0.416 m. The internal resistance (r) of 6 V cell is

The power dissipated in the circuit shown in the figure \(40 \mathrm{~W}\). The value of \(R\) is.
