Final answer:
To calculate the current through each resistor with a color code of brown, black, red, we first determine their resistance (1000 Ω), then find the total circuit resistance for a series circuit, and apply Ohm's Law, given the supply voltage, to find the current.
Step-by-step explanation:
To determine the amount of current through each resistor in the circuit described, you first need to understand how a resistor's value is deciphered from its color bands. A resistor with a color code of brown, black, red corresponds to 1-0 x 100 Ω, or 1,000 Ω because the brown represents the number 1, black represents 0, and red is the multiplier for 100. With the resistance values known, and assuming the circuit is a series circuit based on the provided information, the total resistance (Rtotal) can be calculated by simply adding up all the individual resistance values. Once the total resistance is known, Ohm's Law (V = IR) can be used to find the total current in the circuit, provided the voltage is known. Then, because all components in a series circuit have the same current, this total current value will be the current flowing through each resistor. None of the given current values (a, b, c, d) seem to directly relate to the question asked, as detailed calculations based on given resistances are not provided. More information about the voltage supply would be needed to compute the precise currents.
