Question

ns an a battery of 12 volts? 4.7. What is the current in a circuit when a resistor of 100 ohms is connected in 4.8. What is the current in a circuit whe 4.9. Assume that someone connects a voltmeter in series in error. In that case, what is the current an ammeter of 1 ohm and a battery of 12 volts? an ammeter of O.1 ohm and a battery of 12 volts? in a circuit when a resistor of 100 ohms is connected in series with a voltmeter of 10,000 ohms n a resistor of 100 ohms is connected in series with and a battery of 12 volts?

Explanation / Answer

4.7: I = V / (r + R) = 12 / (1 + 100)

I = 0.1188 A  

4.8 : I= 12 / (0.1 + 100)

I = 0.1199 A  

4.9 I = 12 / (10000 + 10)

I = 1.188 x 10^-3 A
