- R1 = 1.5 Ω R2 = 3.1 Ω R3 = 5.8 Ω Using Kirchhoff's laws, and utilizing the direction in the figure. Find the current I1, I2 and I3A 14-gauge copper wire has a diameter of 1.628 mm. What magnitude current flows when the drift velocity is 1.00 mm/s? (See above example on Example 20.3 for useful information.)E1=5.28mV E2=2.64mV R1=11.6 ohms R2=15 ohms R3=5 ohms I2=I1+I3 Use kirchhoffs rules to solve for the current through R3 in uA (mew amperes)
- All wires shown are made of the same material and have the same diameter. Rank in order, from largest to smallest, the currents I1 to I4 . Explain.In the circuit shown in the figure below, C1=19μF, C2=44μF, C3=20μF, and a voltage Vab=44V is applied accross points a and b. After C1 is fully charged, the switch is thrown to the right. What is the final voltage on C3? Express your answer in units of V(Volts) using one decimal place.The voltage V in a simple electrical circuit is slowly decreasing as the battery wears out. The resistance R is slowly increasing as the resistor heats up. Use Ohm's Law, V = IR, to find how the current I is changing at the moment when R = 356 Ω, I = 0.02 A, dV/dt = −0.01 V/s, and dR/dt = 0.06 Ω/s. (Round your answer to six decimal places.)
- 1. What amount of charge passes through a 3.0 amp television in 1.3 hours?. 2. If 15 coulombs of charge pass through a light bulb in 5 minutes, what amount of current passes through the bulb?Given that R1 = 100 ohms, R2 = 250 ohms, R3 = 350 ohms, and R4 = 100 ohms, how would you find the following for the current pictured? I think I've gotten parts a and b, but I really need to be able to understand. I've never taken a physics class before. Thank you!Determine the magnitudes of the currents through R1 and R2 in (Figure 1), assuming that each battery has an internal resistance r = 1.7 Ω . Express your answers using two significant figures separated by commas.
