The question for me is merely conceptual. I'm really good at math (not that a lot would be required here) but I don't even know where to start, hence the lack of an attempt. I'm not looking for the answer (I already know what it is) I'm just looking for a pointer on how the problem should be solved. Any advice is appreciated!
Voltage is the measure of electric potential energy per unit charge, while amps (or amperage) is the measure of electric current flow. In simpler terms, voltage is the force that pushes the electrons through the circuit, while amps are the actual amount of electrons flowing through the circuit.
Voltage and amps are directly related through Ohm's Law, which states that voltage equals current multiplied by resistance (V = I x R). This means that as voltage increases, current also increases, and vice versa.
The unit of measurement for voltage is volts (V), while the unit for amps is amperes (A). These units can also be expressed in millivolts (mV), kilovolts (kV), milliamps (mA), or kiloamps (kA) depending on the magnitude of the electric charge.
Power is the rate at which energy is transferred or converted, and it is measured in watts (W). The relationship between voltage and power is described by the equation P = V x I, where P is power, V is voltage, and I is current. This means that as voltage increases, power also increases, and vice versa.
The voltage and amps of an electronic device determine its power consumption and performance. Higher voltage and amps can provide more power and faster performance, but it also increases the risk of overheating and damaging the device. It is important to use the recommended voltage and amps for each individual device to ensure safe and optimal performance.
