An 11 Ω resistor is connected across a battery of emf equal to 6 V and internal resistance of 1 Ω. Find: A. the current in the circuit; B. the terminal voltage of the battery; C. the power delivered by the emf; and D. the power delivered to the resistor.

For the circuit shown in the figure below, find the following.   the current in each resistor,I2Ω(top) =,I2Ω(middle) =,I6Ω =,the power supplied by each source of emf P 4V(top) =,the power delivered to each resistorP 1Ω =,P6 Ω =,P2Ω(middle)=

What are the breakdown voltage VZ and Zener resistance RZ of the diode depicted ?

Testing a Battery Without a Tester The internal resistance says a lot about the state of the battery. To calculate the actual internal resistance of the battery, MULTIMETER proceed as follows: • Measure the source voltage (voltage when no current is flowing) (Vo) and terminal voltage (voltage when current is flowing) (Vc). CE CAT I Calculate the voltage drop across the internal resistance OFF V 200m 20M (V, - Vo- Vc). CURRENT CLAMP 2. 2M • Measure the load current (1). Calculate the internal resistance (R = V/ I). OFF 20- -200K 1mV/A 200- 20K 10mV/A 600 2K ... A ZERO 10 200 10 COM The battery being tested has a CCA rating of 640 A. The battery manufacturer specifies that the maximum internal resistance should not exceed 2.5 + cold cranking amps (CCA) rating of the battery. What is the maximum acceptable internal resistance value for this battery?
