A circuit has the following components: a 50 volt power supply and a 2 LIKE resistors that have total resistance of 10 ohms.
Using Ohms Law, solve for I (amperage)

Volts (50) x Resistance (10) = 500a or .5 ma

Volts (50) minus Resistance (10) = 40a

Volts (50) divided by Resistance (10) = 5a

Resistance (10) divided by Volts (50) = .2 a

Ohms Law was created for what reason?

income tax purposes

for measuring wattage

to accurately predict the outcome of a circuit performance

to enable voltage dropping

10 points

Why did the Inventor use "I" to represent Amps instead of "A"?

to adhere to the Electrical code

because his mom was named Isabel

no one really knows

he used a Greek symbol

10 points

Using the pie chart of Ohms Law, How do you calculate for I?

I=VxR

I=VxR2

I=V/R

I=V-R

10 points

Who was the Inventor of Ohms Law ?

George Ohm

Charles Nelson Riley

Hebert Cowsill

Sir Efuss Rednauer

10 points

In a series circuit with LIKE resistors, the voltage across each resistors is......

multiplied using e=mc2

divided by the amps

not measurable

equally split

10 points

You have recently built a circuit for a toy company. Using Ohms Law, you have predicted how the circuit will perform. However, the "measured" outcome is quite different that the "calculated".

What may be the reason for this?

no way of knowing

poor insulation and heat

humidity and ambient temperature

wide resistor "tolerances" and/or voltage problems

10.

10 points

You have a series circuit with four - 100 ohm resistors, all with gold tolerance bands.

R1 measures 96 ohms
R2 measures 105 ohms
R3 measures 106 ohms
R4 measures 95 ohms

Which resistor is OUT of tolerance?
