Best answer

Answer 1

To determine the voltage drop across the 20 Ohm resistor, we need additional information such as the current flowing through the resistor or the total voltage in the circuit.

However, if you have one of the four voltage drop options (-3.00 V, -4.50 V, -6.00 V, -9.00 V) related to a specific current traversing the 20 Ohm resistor, you could use Ohm's Law, which is:

\[ V = I \times R \]

where:
- \( V \) is the voltage drop,
- \( I \) is the current in Amperes,
- \( R \) is the resistance in Ohms.

For example:
- If \( I = 0.15 \, A \) (which is approximately 3.00 V across 20 Ohm),
- If \( I = 0.225 \, A \) (which is approximately 4.50 V across 20 Ohm),
- If \( I = 0.30 \, A \) (which is approximately 6.00 V across 20 Ohm),
- If \( I = 0.45 \, A \) (which is approximately 9.00 V across 20 Ohm).

Without further details about current or a circuit configuration, I cannot definitively select the correct answer from the options provided. Could you please provide the current or circuit details?
