Exercise 2. An instrument used to measure current is called an ammeter. The ammeter is connected into a circuit in series in the loop in which the desired current reading is required. The resistance of an ideal ammeter is zero, and it is essential in real ammeters that the resistance of the instrument be very small compared to other resistances in the circuit. Why? R2 Ri a)-A meter to measure potential difference is called a voltmeter. To find the potential...

Q1. You are given a 12 V DC power supply. You are expected to develop a voltage divider to achieve a voltage of nominal 5V value using a pair of resistors from the E 12 range, with the restrition that you are not expected to draw a current of more than 1 mA from the 12 V DC supply i. Develop a simple circuit showing the possible values for each resistor pair, and the range of the DC output possible...
