A solar cell generates an EMF of 12 V. The terminal potential difference of 9.6 V is measured when a 6 resistor is connected across the battery. What is the internal resistance of the solar cell? The internal resistance, r = Units Select an answer How much power is released in the cell and in the load? The power in the cell, Pinternal = Units Select an answer The power in the load, Puseful = What maximum useful power can be generated by the cell? The max. power, Pmax= Units Select an answer ✓ Units Select an answer

Each of the five resistors has resistance R, and each of the five capacitors has capacitance C. The internal resistance of the battery is negligible. What is the time constant of the circuit shown in figure? R R R TC A. 5 RC B. RC C. 10 RC D. 25 RC

Diagram of the problem, necessary formulas, clearance and numerical solution. An electric light bulb is marked 40 W - 120 V. What is its resistance when it is lit from a 120 V source?

Four resistors are connected as shown below. R₁ = R₂ = R3 = R4 = 3.0 02. The voltage across the battery is 156 V. What is the current through the battery, in Ampere? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. R₂ R₁ ww Hi R₂ R₂
