P = V x I
I = 50 / 12
I = 4.17
R = 50 / (4.17*4.17)
= ~2.88
No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.
Do not add any unwanted device in the circuit. Have correct sized wire for the application and the load current.
This is commonly a problem called "voltage drop". Simply, if you have any power supplying unit connected to an electrical load, it draws an amount of electrical current based on the load value. The voltage at the supply terminals is higher than on the load terminals, this is due to the resistance (impedance) of the connection wires (cables). The more the connection resistance (more resistance means less cross-sectional area), the less the load voltage (if source voltage and load current are kept constants). Another thing that affects the load voltage, is the load current itself. If the load current increases, the load voltage decreases (if source voltage and connection resistance are kept constants). This means that any load current or connection resistance increase mean that the load voltage will decrease. This is exactly what happens in summer. In summer the ambient air temperature is high and hence all connection network elements (wires, cables, TL...) have higher resistance. Plus, most of the air conditioning units operate in summer (higher load current) which represent a bulk load to the network.
Do not add any unwanted device in the circuit. Have correct sized wire for the application and the load current.
How does a fixed bore expansion device respond to a reduction in load?
It is load resistance RL. It can be any device that can act as a load at the output end. Example : A resistor
When two electronic equipments are put one after the other. The input of the last device is the load resistance. Scroll down to related links and look at the first figure of "Calculator Voltage Bridging - Interconnection of Two Audio Units".
It depends on the amount of resistance, or load, the device is on the circuit. Do you have a particular device you're asking about?
It is load resistance RL. It can be any device that can act as a load at the output end. Example : A resistor
Load current is related to load resistance by an inverse relationship. The load current increases linearly as load resistance decreases. Remember, the less resistance, the more current.
The generator sees a resistive load of 3.0 ohms.
No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.
when source resistance and load resistance are equal maximum power is transfered
The resistance arm is the side of the lever (from the fulcrum to the load) that carries the load.
Do not add any unwanted device in the circuit. Have correct sized wire for the application and the load current.
an off-load device a a switch where there is no current passing through it when its switched, a isolator is a off load device, a light switch is a on-load device because there is current passing through it when its switched.
The resistance factors to the current flow in the circuit is what causes the heating effect in a circuit. This resistance usually comes from the load that is connected to the circuit. For example a baseboard heater is a completely resistive load and the result of the heating of the device can be used to heat a room in the home.
