What is the Ohm Law?
Ohm discovered that the amount of current was directly proportional to the voltage (more voltage gives more current) and inversely proportional to the resistance (more resistance gives less current).
Current = Voltage / Resistance
I = V/R (or V = IR, R = V/I)
This relationship is called Ohm's Law. It also gives us a relationship between the units amperes, volts and ohms:
1 ampere = 1 (volt/ohm)
Three coils each having resistance 3 Ω and inductive reactance 4Ω are linked (i) instar and (ii) in delta to a 415V, 3-phase supply. Calculate for each connection (a)
YES GRAVITY CAN BAND LIGHT e.g. GRAVITY OF BACK HOLE IS VERY STRONG
Component Addition of vector We learned in which vectors oriented at right angles to one another could be added together by using the Pythagorean Theorem. For example, two disp
In X-ray tube, when high speed electrons strike the target, they move into the target. They lose their kinetic energy and come to rest inside the solid. The electron because of fin
The neutrons and protons in a stable nucleus are held together by nuclear forces and energy is required to pull them infinitely apart (or the similar energy is released during the
