what potential difference is required to pass 3.0 A through 28 ohm's
Have you heard of Ohm's law?
V = I*R
The answer will be in volts
from ohm law we know that ,
V=IR
I=3 A
R=28 ohms
V=3*28=84 Volts
84V
Yes, you're correct! The potential difference required to pass 3.0 A through a 28 ohm resistor is 84 V.
Well, if you want to pass 3.0 A through 28 ohms, you'll need some shocking humor! Just kidding! To find the potential difference required, you can use Ohm's Law (but don't worry, it's not as boring as it sounds). Ohm's Law states that V (potential difference) equals I (current) multiplied by R (resistance). So in this case, V = 3.0 A × 28 ohms = 84 volts. So, to pass 3.0 A through 28 ohms, you'd need a shocking 84 volts! It's electrifying, isn't it?
To find the potential difference (V) required to pass a current (I) through a resistor with resistance (R), we can use Ohm's Law, which states that V = I * R.
In this case, the current (I) is given as 3.0 A and the resistance (R) is given as 28 ohms. Plugging these values into the formula, we get:
V = 3.0 A * 28 ohms
Now, multiply the current (3.0 A) by the resistance (28 ohms) to calculate the potential difference (V):
V = 84 volts
Therefore, a potential difference of 84 volts is required to pass 3.0 A through a resistor with a resistance of 28 ohms.
