**Question 1:**a. Draw a simple circuit diagram with a battery and a light bulb and explain how you can simultaneously use a voltmeter to measure the voltage drop across the resistor and use an ammeter to measure the current through the resistor. Label both circuit elements along with the current using the notation from Figures 1 and 2.b. If the battery voltage is 2V and the light bulb resistance is 10Ω, what is the current in this circuit?

a) Write an equation for the currents entering in/out of the top junction in Figure 1. Use I1 as the current coming from the left, I2 as the current going downward, and I3 as the current going to the right. b) You can draw three loops in order to solve this circuit. Write the corresponding voltage equations for these loops in terms of V1, V2, VA, and VB; where VA and VB are voltages across the resistors RA and RB respectively. c) Using Ohm's law combined with the equations you found above; express I1, I2, and I3 as equations in terms of the know quantities V1, V2, RA, and RB. d) Now you have all the information you need to express VA and VB as equations in terms of V1, V2, RA, and/or RB.
