The current produced by voltage in a circuit is throttled by electrical r_________ measured in ohms
Electrical resistance!
True or False:
The concept of a "force field" is intended to explain and visualize how non-contact forces can influence objects without touching.
TRUE!
Force fields are visualization tools!
Ohm's Law: V = I x R
The voltage across a 10-ohm resistor carrying 5 A is
A) 50 V. B) 10 V. C) 15 V. D) 20 V.
50 Volts
V = I x R = 5A x 10 ohm = 50 Volt
