- When working with high-power electric circuits, it is advised that whenever possible, you work "one-handed” or “keep one hand in your pocket." Why is this a sensible suggestion?arrow_forwardPower P0 = I0 V0 is delivered to a resistor of resistance R0. If the resistance is doubled (Rnew = 2R0) while the voltage is adjusted such that the current is constant, what are the ratios (a) Pnew/P0 and (b) Vnew/V0? If, instead, the resistance is held constant while Pnew = 2P0, what are the ratios (c) Vnew/V0, and (d) Inew/I0?arrow_forwardThe power dissipated in a resistor is given by P = V2/R, which means power decreases if resistance increases. Yet this power is also given by P = I2R, which means power increases if resistance increases. Explain why there is no contradiction here.arrow_forward
- Show that if two resistors R1and R2are combined and one is much greater than the other (R 1 >>R 2 ): (a) Their series resistance is very nearly equal to the greater resistance R 1. (b) Their parallel resistance is very nearly equal to smaller resistance R2.arrow_forwardPower P0 = I0 V0 is delivered to a resistor of resistance R0. If the resistance is doubled (Rnew = 2R0) while the voltage is adjusted such that the current is constant, what are the ratios (a) Pnew/P0 and (b) Vnew/V0? If, instead, the resistance is held constant while Pnew = 2P0, what are the ratios (c) Vnew/V0, and (d) Inew/I0?arrow_forwardResistors are commonly rated at 18W,14W,12W ,1 W and 2 W for use in electrical circuits. If a current of1 = 2.00 A is accidentally passed through a R=1.00 resistor rated at 1 W, what would be the most probable outcome? Is there anything that can be done to prevent such an accident?arrow_forward
- You wish to measure both the current through and the potential difference across some component of a circuit. It is not possible to do this simultaneously and accurately with ordinary voltmeters and ammeters. Explain why not.arrow_forwardIn the circuit shown, the battery has EMF of c=32 V. At what rate is thermal energy being generated in the 60 resistor? (Ignore the internal resistance of the battery)arrow_forward9. (A) Consider the circuit in Figure on the right and assume the battery has no internal resistance. Just after the switch is closed, what is the current in the battery?

- Two different electrical devices have the same power consumption, but one is meant to be operated on 120-V AC and the other on 240-V AC. (a) What is the ratio of their resistances? (b) What is the ratio of their currents? (c) Assuming its resistance is unaffected, by what factor will the power increase if a 120-V AC device is connected to 240-V AC?arrow_forwardTwo resistors with values of 45 Ω and 50 Ω, respectively, are connected in series and hooked to a 12 V battery. (a) How much current is in the circuit? (b) How much power is expended in the circuit?arrow_forwardTwo identical resistors of 245 Ohms are configured in parallel and connected to a 10.6 V power supply. If the same two resistors are then connected in series, what should the voltage of the power supply be changed to such that the parallel and series configurations draw the same amount of power?arrow_forward
