Answer:
1.Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. ... Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current. Electrons, the most common charge carriers, are negatively charged.
To calculate current, I: put your finger over I, this leaves P over V, so the equation is I = P/ V
2.Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts
To calculate voltage, V: put your finger over V, this leaves P over I, so the equation is V = P/ I
3.Power is defined as the ability to act or have influence over others. An example of power is the strength needed to run five miles. ... Power means to supply with energy or force.
To calculate power, P: put your finger over P, this leaves I V, so the equation is P = I × V.
