Four resistors are connected in a circuit with a battery of unknown emf, as shown below. The battery is ideal, so it has no internal resistance. The current in the 30 Ohm resistor is 120 milliamps. Note that you should be able to do this problem without a calculator. (a) Calculate the current in the 60 Ohm resistor. (b) Calculate the current in the 80 Ohm resistor. (c) Calculate the power dissipated in the 20 Ohm resistor. (d) Calculate the...

You are designing a space heater that can deliver the most power to a person’s upper body 2 m away from the heater. If the device has a maximum current of 15 A and surfaces in the room must stay below 80 degrees Celsius, how might you design such a heater? What do you need to take into consideration? (Open ended question - there is no single correct answer)

EXERCISE NO. 3POWER IN DC CIRCUITSObjectives: The objectives of this exercise are to show how resistor power dissipation is related to voltage, current and resistance in a DC circuit.Procedure: ⦁ Connect the circuit shown in Figure 1 using two 1 kΩ resistors in series. The portable multimeter can be used for the voltmeter. The DMM, used as an ammeter, must be connected in series between the power supply and the resistors.Beginning at 0.0 volts, increase the voltage across the resistors in...

Jimmy the Circuit Builder has seven circuit elements on his workbench. He is trying to build circuits that produce or dissipate specific amounts of power from specific elements. The seven elements are shown below. They include two voltage sources (4 V and 8V), two current sources (5 A and 10 A) and three resistors (31,61 and 91). Each of the sources can produce a maximum of 500W. All elements have a maximum dissipation rating of 1 kW. Jimmy's workbench has...
