Ohm's Law Explained

Ohm's law relates which of the following

• Resistance, Power, Current 

• Power, Voltage and Current

• Voltage, Ohm, Law 

• Current, Resistance and Voltage

Why do you think I is used for current? 

Why is the letter "I" used to represent current? 

• "I" is the first letter in the word current

• "I" don't know 

• "I" stands for Intensity of current

• "I" don't care

V = 

• R/I 

• I/R

• I x R 

I = 

• R/V

• V/R 

• R x V 

R = 

• I/V

• IV

• V/I

What is the Voltage in this example? 

• 1.5 V 

• 2/3 V 

• 6 V 

If you tripled the voltage in a circuit, what would happen to the current? 

• The current would also be tripled because voltage and current are inversely proportional 

• The current would also be tripled because voltage and current are directly proportional 

• The current would be reduces by 1/3 because  voltage and current are inversely proportional 

What is the current in the circuit shown? 

• 1/2 

• 2 A 

• 1/2 A 

• 2 Volts 

What is the relationship between Current and resistance? 

• inverse square

• Exponential 

• Inverse

• Direct
