Question

1два проводника 12 ом и 6 ом соединены параллельно .найдите 1)общее сопротивление 2)напряжение на каждом проводнике ,если во втором проводнике протекает ток 4А 3)силу тока в неизвестной части цепи

Answer 1

1)R=(12*6)/(12+6)=4 Ом
2)U1=U2- по закону о параллельном соединение  U=6*4=24В
3) I=U/R=24/12=2А

Answer 2

Calculation of Total Resistance

To find the total resistance of two resistors connected in parallel, we can use the formula:

1) Total Resistance (R_total) = (R1 * R2) / (R1 + R2)

Given that one resistor has a resistance of 12 Ω (R1) and the other resistor has a resistance of 6 Ω (R2), we can substitute these values into the formula:

1) R_total = (12 * 6) / (12 + 6)

Simplifying the equation:

1) R_total = 72 / 18 = 4 Ω

Therefore, the total resistance of the circuit is 4 Ω.

Calculation of Voltage on Each Conductor

To find the voltage on each conductor, we can use Ohm's Law, which states that voltage (V) is equal to current (I) multiplied by resistance (R):

2) Voltage (V) = Current (I) * Resistance (R)

Given that the current flowing through the second conductor is 4 A, we can calculate the voltage on each conductor using the total resistance of 4 Ω:

2) Voltage on the first conductor = 4 A * 12 Ω = 48 V 2) Voltage on the second conductor = 4 A * 6 Ω = 24 V

Therefore, the voltage on the first conductor is 48 V, and the voltage on the second conductor is 24 V.

Calculation of Current in the Unknown Part of the Circuit

To calculate the current in the unknown part of the circuit, we can use the formula:

3) Current (I) = Voltage (V) / Resistance (R)

However, since the resistance of the unknown part of the circuit is not given, we cannot directly calculate the current. More information is needed to determine the current in the unknown part of the circuit.

Please provide the resistance of the unknown part of the circuit in order to calculate the current.
