Question

Four amperes of current are measured through a 24ohm resistor connected across a voltage source. how much voltage does the source produce

Answer 1

I=4ampere
R=24ohms

V=IR
V=4×24
=96volts.

Answer 2

Answer:

The voltage produced by the source, when 4 amp current is measured through a 24-ohm resistor is 96 volt.

Explanation:

• The movement of positive and negatively charged particles through a conductive material like metal wire per unit time is called an electric current.
• Current is measured by an ammeter, the ampere is the unit for current.
• The potential difference between a given point and a reference point (generally taken as ground) is known as voltage.
• Volt is is the unit for measuring voltage and a voltmeter is used to measure voltage.
• The opposition offered by a conductor to the flow of electric current is termed resistance.
• The passive two-terminal component used to measure resistance is called resistor and ohm (Ω) is used as the unit for resistance.

The relation between the three  electrical components is:

                            current (i) = Voltage (v) / Resistance (R)

Here,

             i = 4 amp

             R = 24 Ω

             V = i × R

                 = 4 × 24

                 =  96 volt

Hence, the voltage produced by the source is 96 volt.
