The diagram shows a potential divider which is used to give outputs of 3V and 6V from a 15V source. What are the correct values of resistors?
Two identical cells are connected to a resistor R and an ammeter in two ways as shown in the diagrams. The current flowing through the ammeter in both circuits are equal. What is the internal resistance of each cell?
An alternating current with the wave form and magnitude shown in the diagram passes through a milliameter calibrated for r.m.s. readings of current. What current, in mA, will the meter record?
In the circuit shown below the internal resistance of the cell is 0.2Ω. The electromotive force of the cell is 6V. What is the voltmeter reading when the current flowing through the cell is 2A?
The diagram shows two resistors of resistance 5000Ω and 2500Ω connected in series. A potential difference of 120V is maintained across them. The potential difference across the 5000Ω resistor is measured using a voltmeter of internal resistance 5000Ω. What is the reading of the voltmeter?
The diagram shows a uniform resistance wire MN of length 100.0cm which is connected to a standard cell of e.m.f. 1.5V and of negligible internal resistance. The circuit is completed with a cell of e.m.f. E, a sensitive galvanometer and a slider P, as shown. When no current flows through the galvanometer, what is the value of E?
