Question: Two resistors R1 and R2 are in series with a
Two resistors R1 and R2 are in series with a 7.0-V battery. If R1 has a resistance of 2.0-Ω and R2 receives energy at the rate of 6.0 W, what is (are) the value(s) for the circuit’s current(s)? (There may be more than one answer.)
Answer to relevant QuestionsFor the circuit in Fig. 18.33, find (a) The current in each resistor, (b) The voltage across each resistor, (c) The power delivered to each resistor, and (d) The total power delivered by the battery. Apply Kirchhoff’s rules to the circuit in Fig. 18.31 to find the current in each resistor. Two identical resistors (R) are connected in parallel and then wired in series to a 40-Ω resistor. If the total equivalent resistance is 55-Ω, what is the value of R? (a) For the circuit in Exercise 36, after the switch has been closed for t = rτ, what is the charge on the capacitor? (b) After a long time has passed, what are the volt-ages across the capacitor and the resistor? A voltmeter has a resistance of 30-kΩ. (a) Sketch the circuit diagram and find the current in a 10-Ω resistor that is in series with a 6.0 V ideal battery when the volt-meter is properly connected across that 10-Ω ...
