Question

VERY SHORT ANSWER TYP
1. Define S.I. unit and formule

(a) Electric current
(b) Potential difference
(C) Resistance
(d) Electric power
(e) Electrical energy consumed​

Answer 1

1.ampere

2.volt

3.ohm

4.watt

5.joule

Answer 2

Answer:

Electric Current;

Current electricity is a constant flow of electrons.

S.l unit;

SI Base Unit: Ampere

Formula;

I= V/R.

Potential Difference;

Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit. .

SI unit.unit: volt

Formula

Ohm's law

V = IR

Resistance;

Resistance has units of ohms (Ω), related to volts and amperes by 1 Ω = 1 V/A. There is a voltage or IR drop across a resistor, caused by the current flowing through it,

Formula;

given by V = IR.

Electric Power;

lElectric power measure of the rate of electrical energy transfer by an electric circuit per unit time

Formula;

P= V*I.

SI unit= watt

Electrical energy cunsumption

In electrical engineering, power consumption refers to the electrical energy per unit time, supplied to operate something, such as a home appliance.

Unit;

KW

Once you have your data, calculate the cost of use with this formula:

1. Multiply the device's wattage by the number of hours the appliance is used per day.
2. Divide by 1000.
3. Multiply by your kWh rate.
