Step 1
Given: E = 120.0 V R1 = 40.0 Ω R2 = 20.0 Ω Using Ohm's Law: i1 = E / (R1 + R2) i1 = 120.0 / (40.0 + 20.0) i1 = 120.0 / 60.0 i1 = 2.0 A i2 = E / R2 i2 = 120.0 / 20.0 i2 = 6.0 A ** Show more…

For the circuit shown in the figure, determine the magnitude of the currents I2, I3, and I4 passing through batteries 2, 3, and 4, respectively. In each case, determine whether the battery is supplying power or being charged. The batteries and resistors in the circuit are assumed to be ideal and have the given properties. E1 = 24.0 V E2 = 4.50 V E3 = 18.0 V E4 = 3.00 V R1 = 35.0 Ω R2 = 30.0 Ω R3 = 82.0 Ω Battery 2 is supplying power.

Each of the four circuits in the drawing consists of a single resistor whose resistance is either $R$ or $2 R,$ and a single battery whose voltage is either $V$ or $2 V$. Rank the circuits according to (a) the power and (b) the current delivered to the resistor, largest to smallest. Explain your answers. Problem The unit of voltage in each circuit is $V=12.0 \mathrm{~V}$ and the unit of resistance is $R=6.00 \Omega .$ Determine (a) the power supplied to each resistor and (b) the current delivered to each resistor. Check to see that your answers are consistent with your answers to the Concept Questions.
