The current (I) in an electrical conductor varies inversely as the resistance (R) of the conductor. The current is 6 amperes whe n the resistance is 722 ohms. What is the current when the resistance is 768 ohms? Round your answer to two decimal places if necessary.
2 answers:
Basically, this is Ohm's Law: V=RI where V is the tension in volts; You have that V=722×6=4332 Volts Using this value for V you have that: 4332=768×I So I=5.64 A
Answer:
The current is 5.64 Ampere when resistance is 768 ohms .
Step-by-step explanation:
As given
The current (I) in an electrical conductor varies inversely as the resistance (R) of the conductor.
Thus
Where k is the constant of proportionality .
The current is 6 amperes when the resistance is 722 ohms.
I = 6 amperes
R = 722 ohms
Put all the values in the formula
k = 6 × 722
k = 4332
As given
when the resistance is 768 ohms .
R = 768 ohms
K = 4332
Put in the formula .
I = 5.64 Ampere
Therefore the current is 5.64 Ampere when resistance is 768 ohms .
