Three resistors, 25, 45, and 75 Ω, are connected in series, and a 0.51-A current passes through them. What are (a) the equivalent resistance and (b) the potential difference across the threeresistors?

If all of the resistors are 4.7 k, what is the value of RT?

What is the smallest resistance you can make by combining them?

A circuit consisting of three ideal batteries with voltages E1, E2, and E3, and three ideal resistors with resistances R1, R2, and R3, is shown in the figure. Calculate the current IP through point P. Let the sign of the current correspond to its direction, with "up" being positive. E1=17.5 V, E2=15.0 V, E3=30.0 V ?1=3.90 kΩ, ?2=13.0 kΩ, ?3=8.75 kΩ

In the circuit shown in the diagram below, two thick wires connect a 1.5 volt battery to a Nichrome (NiCr) wire. Each thick connecting wire is 17 cm long, and has a radius of 9 mm. The thick wires are made of copper, which has 8.36e+28 mobile electrons per cubic meter, and an electron mobility of 0.00434 (m/s)/(V/m). The Nichrome wire is 8 cm long, and has a radius of 4 mm. Nichrome has 9e+28 mobile electrons per cubic meter, and an electron mobility of 7e-05 (m/s)/(V/m). What is the magnitude of the electric field in the thick copper wire? V/m What is the magnitude of the electric field in the thin Nichrome wire? V/m Copper Copper Nichrome
