Question

Чему равно полное сопротивление цепи , если эдс источника 8в а сила тока 2а

Answer 1

Формула I=эдс/ R+r, где r это внутреннее сопротивление, значит полное сопротивление равно R+r=8/2=4

Answer 2

Calculation of Total Resistance in a Circuit

To calculate the total resistance in a circuit, we can use Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance. Ohm's Law can be expressed as:

V = I * R

Where: - V is the voltage (electromotive force) in volts (V) - I is the current in amperes (A) - R is the resistance in ohms (Ω)

In this case, we are given that the electromotive force (EMF) or voltage of the source (EDS) is 8V and the current flowing through the circuit is 2A.

Using Ohm's Law, we can rearrange the formula to solve for resistance:

R = V / I

Substituting the given values:

R = 8V / 2A

Calculating the result:

R = 4Ω

Therefore, the total resistance in the circuit is 4 ohms.
