I have two problems of electricity: 1. http://i56.tinypic.com/2a6rnzs.jpg" i.Use Kirchoff's first law to find the current through the 4.00 ohm and 8.00 ohm resistors ii. Calculate the emf E1 iii. Calculat the emf E2 iv. Calculate the current through the 12.00 ohm resistor 2. A student builds the circuit in the diagram, using a battery of negligible internal resistance. The reading on the voltmeter is 9.0V. http://i55.tinypic.com/ic5vgi.jpg" i.The voltmeter has a resistance of 1200 ohm. calculate the emf of the battery. ii. The student now repeats the experiment using a voltmeter of resistance 12 Kiloohm. Show that the reading on this voltmeter would be 9.5V iii. Refer to your answers in i. and ii. and explain why a voltmeter should have as high a resistance as possible.
