resistance is measured in ohms (Ω). An ohm is the resistance that occurs when a current of one ampere (A) passes through a resistor with a one volt (V) drop across its terminals. The current is proportional to the voltage across the terminal ends. This ratio is represented byOhm’s ...
The flow of electric charge in only one direction is known as direct current (DC). DC is also referred to as “DC Current”. Although this is technically saying the same thing twice “Direct Current Current”. As DC flows only in one direction; hence it is also referred to as unidirecti...
Ohms are sometimes expressed inpower-of-10multiples to accommodate large quantities. For example, one kiloohm is equal to 1,000 (103) ohms, and one megaohm is equal to 1,000 kiloohms or 1,000,000 (106) ohms. In addition, ohms can be expressed in smaller quantities, such as the micro...
An ohmic resistor is made ohmic because its function follows Ohm's law. Ohm's law essentially says that current is equal to voltage divided by resistance. Additionally, resistance is equal to voltage divided by current, and voltage is equal to current times resistance. Therefore, in a circuit,...
noticed how you feel like your weight is been reduced while the elevator goes down? that is because the weight you feel is the perceived weight or “effective weight”, this is the equal and opposite force the floor exerts on you due to your weight. now if we remove the floor and let...
Above is the potential energy formula. As per thelaw of conservation of energy, since the work done on the object is equal to m×g×h, the energy gained by the object = m×g×h, which in this case is the potential energy E. ...
If we translate these three equations into words, we will have a good explanation of Ohm’s law: If a current I is flowing through a component with a resistance R, the voltage across that component is equal to I multiplied by R. If a voltage V i...
Shunt Resistor Definition: A shunt resistor is a device with low resistance used to direct most of the circuit’s current through a specified path. Connection Method: Shunt resistors are connected in parallel with measurement devices like ammeters to maintain equal voltage across them. Using Ohm’...
Identify the Power Rating:Check the appliance’s label or manual to find its power rating, usually given in watts (W) or kilowatts (kW). If the rating is in watts, you can convert it to kilowatts by dividing by 1,000. For instance, 500 watts is equal to 0.5 kW. ...
