2. In the circuit resistor A is 30 ohm, resistor B is 20 ohm, and resistor C is 10 ohm. a) Calculate the current through each resistor. You may do this either by solving the equations obtained from Kimhois rules or byrstnding the equivalent resistance of the whole circuit and then determining how current must split at the junction. . b) Build this circuit using the PhET simulation. Show how you would use a voltmeter and ammeter to measure the voltage across and the current through resistor B, respectively. Attach a screenshot.

Be sure to state the unit. d) At one instant the wire just above resistor B suddenly breaks so that current can no longer flow through resistor B. Explain, by either qualitative or quantitative arguments, whether the current through each remaining resistor increases, decreases, or remains the same
