Which equation should be used to calculate how much current in amps is required to achieve the full 100 W output from the 9 V bulb?

I = p/v = 100w/9v = 11.11ai = p*v = 100w*9v = 900ai = (p/2)*v = 50w*9v = 450ai = p*2*v = 100w*(9v + 9v) = 8100a


How do you calculate the current required to melt 14 gauge wire insulation?

To calculate the current required to melt 14 gauge wire insulation, you need to know the specific heat capacity and melting point of the insulation material. You then use the formula Q = mcΔT to calculate the heat energy required to melt the insulation, where Q is the heat energy, m is the mass of the insulation, c is the specific heat capacity, and ΔT is the temperature increase needed to reach the melting point. The current can be estimated using the formula I = Q / t, where I is the current, Q is the heat energy calculated earlier, and t is the time over which the heat is applied.


What is the formula of ilkovic equation in the diffusion current?

ilkovic equation gives us the chance to know what is the potential difference of any system.the potential difference can easily be calculated with the help of Hg-drop!there is an equation with the help of which we can know very other things except the potential difference!


How many volts is 450 watts?

To calculate the voltage, you need to know the current (amperage) as well. The formula to calculate power (watts) given voltage (volts) and current (amps) is: Power (P) = Voltage (V) x Current (I). Without knowing the current, it is not possible to directly convert watts to volts.


How do you calculate current and voltage passing through light globes?

To calculate current passing through a light globe, you can use Ohm's Law: current (I) = voltage (V) / resistance (R). To calculate voltage across a light globe, you can rearrange Ohm's Law to solve for voltage: voltage (V) = current (I) * resistance (R). Just make sure you know the resistance of the light globe in ohms.
