Find the Thevenin equivalent with respect to the terminals a and b for the circuit in Figure P2.

In the circuit in the diagram below the meter M which has the internal resistance R goes to exactly half full-scale deflection (FSD). The shunt resistance is now removed and replaced as a series resistance. Surprisingly, the meter reads the same again, exactly half FSD. Find the resistance R of the meter and hence state the current through the meter at FSD and the voltage across the meter at FSD. 12V 20Ω M 200 R

In the circuit below, the currents through the four resistors are as indicated. Use the junction rule to write the equations representing the relationship between the currents at the point d. (Use the following as necessary: 14, 15, and 16.) 16=14+15 X = 0 &₁ 15 R4 d E₂ =&

A potentiometer consisting of a wire of length L0 has a source of emf, ɛ connected across it. When a standard cell with emf V = 6V, in series with a voltmeter, is connected at one end of the wire and at a distance L = 4 cm along the wire the voltmeter circuit is in balance and the voltmeter reads zero. When the standard cell is replaced by a source of unknown emf the new balance length is found to be 6 cm.   What is the unknown emf? Select one: a. 8 V b. 9 V c. 4 V d. 3 V

A Wheatstone bridge is used for measuriug the valuc of change of resistance of a strain gauge wnich forms one of the arms of the bridge. All tbe arms of the bridge including the strain gauge have a resistance of 100 N each. The maximum a!lowable power dissipation from the strain gauge is 250 mW. Determine the value of maximu:n permissible current through the strain gauge and maximum allowable value of bridge supply voltage. Suppose a source of 20 V is available, lind the value of series resistance to be connected between the source and the bridge to limit the input voltage of the bridge to permissible level.
