Current (I) is a rate of flow and is measured in amps (A). Ohms (R) is a measure of resistance and is analogous to the water pipe size. Current is proportional to the diameter of the pipe or the amount of water flowing at that pressure. Voltage is an expression of the available e...
To understand the difference between an amp and a joule, you need to understand voltage. Voltage is the difference between the number of electrons in one place and the number in another. Imagine that you have not yet turned on the hose full of molasses. There is a lot of molasses waiting...
When using amps mathematically, amps equal the watts divided by the volts of an appliance. So, the formula looks like this: Amps = Watts/Volts Let’s say we’re calculating the amps of an appliance, and we know that its wattage is 3000W and voltage is 200V. Using our formula, we ca...
Most conventional amps have a power supply that will decrease in voltage if driven with a lot of loud bass. If you highpass that amp, you virualy increase the supply voltage. Which gives the remaining frequency range more headroom before ...
Understanding the relationship between amps and other electrical units is essential to grasp the full picture of electrical systems. Let's explore the relationships between amps, volts, ohms, and watts: Amps and Volts:Volts (V) represent the unit of electrical potential difference or voltage. Curre...
Where stands for amperes or amps (the units for electric current). Example As shown in the circuit below, a supply voltage of is applied to a lamp. Determine the current taken by the lamp. Solution: Given Data: According to formula, Thus, using the equation above we get the current ta...
Opamps amplify the differential voltage based on the opamp's amplification factor, with the output voltage expressed as follows. Therefore, When the open gain Av of the opamp is sufficiently large, the left-hand side can be approximated to 0, and Vs=VOUT. If the gain is low, the left-ha...
How to size your charge controller (mppt vs pwm) Overall, charge controller sizing is not as difficult as you may think. Charge controllers are rated and sized depending on your solar array's current and the solar system’s voltage. You typically want to make sure you have a charge control...
A 12V AC to DC converter is an electronic device that changes the voltage of an alternating current power source to a direct current power source. This converter is specifically designed for LED lights, which require a constant DC voltage to function properly. Why do we need a 12V AC to DC...
If adiodehas S-factor equals to unity it is known as a soft-recovery diode and for S-factor less that unity it is known as fast or snappy-recovery diodes. S-factor indirectly indicates the voltage transient that occurs upon the turn off of the diode. Low S-factor implies high transient...
