Answer 1

To calculate the current flowing through R1 in the circuit, use Ohm's law: I = V / R. Substitute the given values to find the current.

Step-by-step explanation:

Based on the given information, it seems that the question is about calculating voltages and resistances in a circuit. The values provided are V1 = 680 Ohms

, V2 = 560 Ohms,

and V = 66.959 V.

To find the current through each resistor, we can use Ohm's law: I = V / R.

For R1, the current (IR1) is calculated as IR1 = V / R = 66.959 V / 680 Ω

= 0.0982 A (or 98.2 mA).

Answer 2

To find the IR drop in R₁, we note that the full current I flows through R₁. Thus its IR drop is V₁ = IR₁. The total current I is found using Ohm's law for the circuit. The value of I can then be used to calculate V₁.

To find the IR drop in R₁, we note that the full current I flows through R₁. Thus its IR drop is V₁ = IR₁. We must find I before we can calculate V₁. The total current I is found using Ohm's law for the circuit. That is, V_total = I * R_total.

From the given values, V = 66.959 V and R_total = R₁ + R₂ = 680 Ohms + 560 Ohms = 1240 Ohms. Plugging in these values, we can solve for I: I = V_total / R_total = 66.959 V / 1240 Ohms = 0.0538 A. Now we can calculate V₁ using Ohm's law for R₁: V₁ = I * R₁ = 0.0538 A * 680 Ohms = 36.5 V.
