Questions 1) Ammeters must always be connected in 1
2) Voltmeters must always be connected in 1
3) Suppose an ammeter (internal resistance of 5Ω ) was mistakenly connected in parallel with a 100Ω resistor.
a. What is the effective equivalent resistance of the 100Ω resistor and 5Ω ammeter connected in parallel?
b. From Ohm's Law, what current will flow through the circuit when connect to a 20 V power supply?
4) Suppose a voltmeter (internal resistance of 10MΩ ) was mistakenly connected in series with a 100Ω resistor.
a. What is the effective equivalent resistance of the 100Ω resistor and 10MΩ voltmeter connected in series?
b. From Ohm's Law, what current will flow through the circuit when connect to a 20 V power supply?
