Answer:
Explanation:
As we know by the principle of uncertainty that the product of uncertainty in position and uncertainty in momentum is given as
so here we know that
so we have
explain how you can determine how much power a circuit will generate if you know the voltage and resistance but not the current
1 answer:
The general formula for power dissipation is:
Power = Current x Voltage
However, if you only know the voltage and the resistance, you can calculate the current using Ohm's Law, which is usually given as:
Voltage = Current x Resistance
However, you can rearrange this to give:
Current = Voltage/Resistance
You can then substitute this into the expression for power dissipation to yield an equation that gives an expression for power in terms of only voltage and resistance:
Power =
/ Resistance
Power = Current x Voltage
However, if you only know the voltage and the resistance, you can calculate the current using Ohm's Law, which is usually given as:
Voltage = Current x Resistance
However, you can rearrange this to give:
Current = Voltage/Resistance
You can then substitute this into the expression for power dissipation to yield an equation that gives an expression for power in terms of only voltage and resistance:
Power =
