Suppose we need to design a voltage-divider circuit to provide an output voltage vo = 5V from a 15-V source as shown in Figure P2.40. The current taken from the 15-V source is to be 200 mA. a. Find the values of R1 and R2. b. Now suppose that a load resistance of 200 Ω is connected across the output terminals (i.e., in parallel with R2 ). Find the value of vo.
A d.c. source has an open-circuit voltage of 30V and an internal resistance of 1.5 Ω.
State the value of load resistance that gives maximum power dissipation and determine the value of this power.
The coil of a measuring instrument has a resistance of 1-ohm and the instrument has a full scale deflection of 250 V when a resistance of 4999 is connected with it. Draw a circuit by using given data and Solve it to find the full scale current of the PMMC meter when used as voltmeter.

- Create a circuit diagram using the instructions given then find its Requivalent.arrow_forwardMost sources of electrical power behave as (approximately) ideal voltage sources. In this case, if we have several loads that we want to operate independently, we place the loads in parallel with a switch in series with each load. Thereupon, we can switch each load on or off without affecting the power delivered to the other loads. How would we connect the loads and switches if the source is an ideal independent current source?
