The ideal battery in Figure (a) has emf = 8.1 V. Plot 1 in Figure (b) gives the electric potential difference V that can appear across resistor 1 of the circuit versus the current i in that resistor. The scale of the V axis is set by Vs = 19.5 V, and the scale of the i axis is set by is = 3.00 mA. Plots 2 and 3 are similar plots for resistors 2 and 3, respectively. What is the...
please help with A and B If the battery in (Figure 1) were ideal, lightbulb A would not dim when the switch is closed. However, real batteries have a small internal resistance, which we can model as the 0.31 resistor shown inside the battery. In this case, the brightness of bulb A changes when the switch is closed. Assume E = 1.7 V. Figure 1 of 1 0.3.2 A 6.0 22 16.02 E Part A How much power does bulb...
