- If electrons travel from the negative to the positive terminal of an 8-volt battery. How much energy could be supplied? Express your answer in nano(n). Please include detailed solution. I will attach the reference formulas that we use. The value of k is 8.99 x 10^9, not rounded off to 9. Thank you!A circuit consists of two 100-kΩ resistors in series with an ideal 12.0-V battery. Calculate the potential drop across one of the resistors. A voltmeter with internal resistance 10.0 MΩ is connected in parallel with one of the two resistors to measure the potential drop across the resistor. By what percentage will the voltmeter reading deviate from the value you determined in part (a)? (Hint: The difference is rather small, so itis helpful to solve algebraically first to avoid a rounding error.)In the left figure, create two formulations/equations of the currents IT, I1, I2, & I3 using the conceptof KCL. On the other hand, create two formulations/equations of the given voltages using theconcept of KVL on the right figure.
