The correct relation between charge(Q) flowing through a conductor, time(t) for which the charge flows and the current (I) flowing through the conductor is:
I=Qt2
I=Qt
I=Q2t
I=tQтАЛ
I=tQтАЛ
Electric current (I) is defined as the rate of flow of electric charge through a cross-section of a conductor per unit time. Mathematically, it is the ratio of total charge (Q) to the time (t) taken for that charge to pass through.
Electric current (I) is defined as the rate of flow of electric charge through a cross-section of a conductor per unit time. Mathematically, it is the ratio of total charge (Q) to the time (t) taken for that charge to pass through.
Think of water flowing through a pipe: current is like the rate of water flow (liters per second), while the charge is the total volume of water passing through the pipe in a specific duration.
Remember 'IQuit Today' for I=Q/t (I = Q/t).
I=tQтАЛ тАФ Definition of electric current as charge per unit time
Q=I├Чt тАФ Expression for total charge transferred
According to the fundamental definition of electricity, current represents the flow of charge carriers (usually electrons) through a material. If a charge Q passes through a conductor in time t, the average current is expressed as I=tQтАЛ. The SI unit of current is the Ampere (A), where 1A=1C/s.
Current is a scalar quantity in basic circuit analysis.
Charge (Q) is measured in Coulombs (C).
Time (t) must be measured in seconds (s) for the current to be in Amperes (A).
Provides a simple, universal way to quantify electron flow in any circuit.
Calculating battery capacity in Ampere-hours (Ah).
Determining fuse ratings for electrical appliances.
The SI unit of electric current is the Ampere (A), named after Andr├й-Marie Amp├иre.
Options A, B, and C are physically incorrect as they do not represent the definition of current and lead to inconsistent units.
D is correct тАФ The electric current is defined as the rate of flow of electric charge, given by the formula I=tQтАЛ.
Always check the units: 1┬аAmpere=1┬аCoulomb/1┬аsecond. If an equation doesn't satisfy dimensional analysis, it is likely incorrect.
