Question

The peak current through a resistor is 2. 0 aa. part a what is the peak current if the resistance rr is doubled?

Answer 1

When the resistance R is doubled, I = 1 A

One of the most fundamental and significant principles controlling electrical and electronic circuits is called Ohm's Law. For a linear device, it relates current, voltage, and resistance.

According to Ohm's Law, the current flowing through a circuit is inversely proportional to the resistance in the circuit and directly proportional to the applied potential difference.

Ohm's law can be written mathematically as follows:

V = IR

Where:

   V = voltage expressed in Volts

   I = current expressed in Amps

   R = resistance expressed in Ohms

If any two quantities are known, the third can be computed by manipulating the formula.

   I= V/R

   R= V/I
