Question

According to Ohm’s law, determine the calculated current for these values in Table A. voltage = 5 V, resistance = 20 Ω: A voltage = 20 V, resistance = 20 Ω: A voltage = 50 V, resistance = 20 Ω: A

Answer 1

0.25 A

1.00 A

2.50 A

Step-by-step explanation:

Answer 2

0.25 A, 1.00 A, 2.50 A

Step-by-step explanation:

Ohm's law is summarized by the equation:

`V=RI`

where

V is the voltage

R is the resistance

I is the current

Re-arranging it, we have an expression for the current:

`I=(V)/(R)`

Solving for the different cases, we have:

voltage = 5 V, resistance = 20 Ω:
`I=(5)/(20)=0.25 A`

voltage = 20 V, resistance = 20 Ω:
`I=(20)/(20)=1.00 A`

voltage = 50 V, resistance = 20 Ω:
`I=(50)/(20)=2.50 A`
