In order to calculate the series resistance required to obtain a regulated output of 30V, we need to determine the voltage drop across the series resistance.
The total voltage across the three Zener diodes is 10V x 3 = 30V.
Since the desired output voltage is also 30V, the voltage drop across the series resistance will be 45V - 30V = 15V.
Now, we can use Ohm's Law to calculate the series resistance. Ohm's Law states that the voltage across a resistor is equal to the current flowing through it multiplied by its resistance.
In this case, the current flowing through the circuit is 1000mA = 1A.
So, using Ohm's Law, we can write:
15V = 1A x R
R = 15V / 1A
R = 15Ω
Therefore, the series resistance required to obtain a regulated output of 30V is 15Ω.
The total voltage across the three Zener diodes is 10V x 3 = 30V.
Since the desired output voltage is also 30V, the voltage drop across the series resistance will be 45V - 30V = 15V.
Now, we can use Ohm's Law to calculate the series resistance. Ohm's Law states that the voltage across a resistor is equal to the current flowing through it multiplied by its resistance.
In this case, the current flowing through the circuit is 1000mA = 1A.
So, using Ohm's Law, we can write:
15V = 1A x R
R = 15V / 1A
R = 15Ω
Therefore, the series resistance required to obtain a regulated output of 30V is 15Ω.
