Question: 1. How much current is flowing through a wire if 21.5 C of charge passes a point in 6.3 seconds? 2. A 210 ? resistor

1. How much current is flowing through a wire if 21.5 C of charge passes a point in 6.3 seconds?

2. A 210 ? resistor is connected in a circuit with a 110 V battery. How much charge passes through a point in the circuit in two minutes?

3. How long would these devices need to be in operation before 1,000,000 C of charge passes through them? a. LED night light (I = 0.0041 A) b. incandescent night light (I = 0.052 A) c. 60 W incandescent light bulb (I = 0.4 A) d. large light fixture (I = 2.1 A)

4. An electric saw at a local hardware store features a motor that supplies 15 A. Find the resistance of the saw when it is plugged into a 110 V outlet.

5. Defibrillator machines are used to deliver an electric shock to the human heart and resuscitate a heart that has stopped beating. A current as low as 18 mA can trigger resuscitation. Using 95 k? as the resistance, determine the minimum output voltage needed by a defibrillator for it to be effective.

6. A taser sends about 1100 V through the human body, resulting in an average current of 2.5 mA. Using these numbers, estimate the electrical resistance of the human body.

7. A. Resistivity indicates the overall resistance of a material. It is measured by units of ?m and depends on material type. To determine the resistivity of a wire, divide its length by its area as indicated in the diagram below:
