It has been claimed that if a human body is exposed for just 1 tenth of a second to a current of 70mA in an rms voltage of 120V at a frequency of 60Hz this could lead to deadly consequences. What would be the resistance of the body in such a situation?

The figure below shows three lightbulbs connected to a 120-V AC (rms) household supply voltage. Bulbs 1 and 2 have a power rating of 75 W, and bulb 3 has a 40-W rating. 120 V 1 2 3 (a) Find the rms current in each bulb. Ibulb 1 = A Ibulb 2 = A Ibulb 3 = A (b) Find the resistance of each bulb. Ω Rbulb 1 = Rbulb 2 = Ω Rbulb 3 2 i (c) What is the total resistance of the combination of the three lightbulbs? Ω

A DC circuit consists of a 30.5 V battery connected in series to two components. The first component is a variable resistor set to 1.7 Ohms. The second component is a set of four fixed resistors connected in parallel. The first fixed resistor is 7.9 Ohms, the second fixed resistor is 6.5 Ohms, the third fixed resistor is 5.3 Ohms and the fourth fixed resistor is 7.9 Ohms. What is the total current supplied by the battery to the circuit? Use standard abbreviations for MKS units. Your Answer: Answer units

Q14

In an RLC circuit, the resistance R does NOT change with frequency. Why would VR change with frequency(consider other factors in the circuit).
