The current in a long solenoid is increasing linearly with time, so the flux is proportional to t: = αt. Two voltmeters are connected to diametrically opposite points (A and B), together with resistors \left(R_{1} \text { and } R_{2}\right), as shown in Fig. 7.55. What is the reading on each voltmeter? Assume that these are ideal voltmeters that draw negligible current (they have huge internal resistance), and that a voltmeter registers -\int_{a}^{b} E \cdot d l between the terminals and through the meter. [Answer: V_{1}=\alpha R_{1} /\left(R_{1}+R_{2}\right) ; V_{2}=-\alpha R_{2} /\left(R_{1}+R_{2}\right) . \text { Notice that } V_{1} \neq V_{2} , even though they are connected to the same pointss !^{32}]
