the hot resistance of an incandescent lamp is 220 ohms. it requires 1/2 amp to cause it to glow.
2.A certain milliameter, with a scale of 0 to 1.0 mA, has a resistance of 32 ohms. if this milliameter is connected directly across a 120-volt line, how much current will flow through the meter?
3. The ammeter-voltmeter method is used to measure an unknown resistance R. An ammeter (A) connected in series with the resistance reads 0.3 R. A voltmeter (V) placed across the ends of the resistance reads 1.5V. compute the value of resistance R.
