Question

1.Четыре резистора сопротивлением 2 Ом, 3 Ом, 1,5 Ом 3,5 Ом соединены и последовательно. Определите Общее сопротивление и общую силу тока в цепи, если напряжение во всей цепи 18 В.

Answer 1

Ответ:

R= 10 Ом

I= 1,8 А

Объяснение:

При последовательном соединении сопротивление складывается

2+3+1,5+3,5=10 Ом

По закону ома находи силу тока

I=U/R

I=18/10

I=1,8 A.

Answer 2

Calculation of Total Resistance and Total Current

To determine the total resistance and total current in the circuit, we need to calculate the equivalent resistance of the four resistors connected in series.

Given resistances: - Resistor 1: 2 Ω - Resistor 2: 3 Ω - Resistor 3: 1.5 Ω - Resistor 4: 3.5 Ω

To find the total resistance, we add up the individual resistances:

Total Resistance = Resistor 1 + Resistor 2 + Resistor 3 + Resistor 4

Total Resistance = 2 Ω + 3 Ω + 1.5 Ω + 3.5 Ω

Total Resistance = 10 Ω .

Now, to calculate the total current in the circuit, we can use Ohm's Law:

Total Current = Voltage / Total Resistance

Given voltage: 18 V

Total Current = 18 V / 10 Ω

Total Current = 1.8 A

Therefore, the total resistance in the circuit is 10 Ω and the total current is 1.8 A when the voltage across the circuit is 18 V.
