You should not touch electrical appliances with wet hands because wet hands will result in:
Select one or more
Touching electrical appliances with wet hands results in lower resistance as water is a good conductor of heat
Please rate it up thanks :)

Current, Electric Potential, Ohm's Law Problem 19.34: Electrical safety. This procedure is not recommended! You'll see why after you work the problem. You are on an aluminum ladder that is standing on the ground, trying to fix an electrical connection with a metal screwdriver having a metal handle. Your body is wet because you are sweating from the exertion; therefore, it has a resistance of 1.80 k? -Part A If you accidentally touch the "hot" wire connected to the 120...
The capacity of a storage battery, such as those used in automobile electrical systems, is rated in ampere-hours (A · h). A 50-A · h battery can supply a current of 50 A for 1.0 h, or 25 A for 2.0 h, and so on. Consider a 12.0-V battery that has an internal resistance of 0.26 Ω and a capacity of 55.8 A · h. The battery is charged by passing a 9-A current through it for 6.2 h. (a)...

1. For the shown circuit with 2 electrical equipment (2 loads), R1 = 60 Ω R2 = 30 Ω ET = Vt = 120 V E: the potential difference in Volts Calculate the following: a) RT (total Resistance) b) IT (Total Current) c) IR1 (Current in equipment R1) d) IR2 (Current in equipment R2) e) VR2 (Voltage across R2) No circuit diagram was given. Just need the calculations from A - E.
Answer: Please help! Electrical series circuits never make sence to me. I included the answer so that you can check your work. Hope that helps. 19. An electrical series circuit contains a resistor with a resistance of R- 20 ohms, a capacitor with a capacitance of C 0.01 farads, and an inductor with an inductance of L 1 henry. The initial current in the circuit is 0 amperes. A variable voltage of E(t) 120 sin volts of is applied to...

A sliding metalic bar with no electrical resistance is made to move to the right ntol parallel conducting rails are placed a distance I apart with a magnetic field B to the paper. The rails are connected with a fixed wire whose electrical with a constant speed v (left side of diagram above) a. In order to be consistent with...
6. You and a friend rent a room in an old house and find that if both of you are using your blow dryers, the 20 amp fuse for that circuit occasionally blows. Each blow dryer has a high and a low power setting, which has the effect of fixing the electrical resistance. The wire from the fuse box is as old as the house, and has an additional resistance which newer wiring would minimize. W 120V 120V Powerline R2...
