Question

Е=1,5в R=5,2 ом ч=08 ом ч-? U-?​

Answer 1

I=E/(R+r) =1,5/(5,2+0,8)= 0,25 A

U=I*R=0.25*5.2= 1.3 Вольта

Answer 2

It appears that your message contains a mix of symbols and letters that are not entirely clear. However, I will do my best to interpret what you might be asking.

From the information provided, it seems you have values for electric potential (U or voltage) and resistance (R) in a circuit. Additionally, there are two unknowns, represented by the symbols ч and U.

Let's clarify the given values:

• Electric potential (U) = 1.5 volts (V)
• Resistance (R) = 5.2 ohms (Ω)
• Some unknown value (ч) = 0.8 ohms (Ω)

Now, let's calculate the unknowns:

1. The current (I) can be calculated using Ohm's Law: I = U / R
2. We can then find the voltage drop (U') across the unknown resistor (ч) using Ohm's Law: U' = I * ч

Step 1: Calculate the current (I): I = 1.5 V / 5.2 Ω ≈ 0.28846153846 A (approximately 0.29 Amperes)

Step 2: Calculate the voltage drop (U') across the unknown resistor (ч): U' = 0.29 A * 0.8 Ω = 0.232 V (approximately 0.23 Volts)

So, the current (I) in the circuit is approximately 0.29 Amperes, and the voltage drop (U') across the unknown resistor (ч) is approximately 0.23 Volts.
