Ohm's law is V=IR, power is P=IV. In this question, the voltage powering a circuit is the due date month while the current is the due date day. For example, if the due date is 7/2 then the circuit has 7 Volts with 2 Amps for voltage and current, respectively. Do not use 7 Volts and 2 Amps unless the due date is 7/2. Be sure to include units in responses.
1) Write the voltage and current based on due date as described above.
2) Given the voltage and current in part 1) what is the resistance of the circuit?
3) What is the power exhibited in this circuit? (V-A would be units of Watts)
Answer (2)
To solve the question based on Ohm's Law and the Power formula, here are the steps you'll need to follow:
Write the voltage and current based on due date as described:
According to the problem, the voltage (V) is the month of the due date, and the current (I) is the day of the due date. Let's assume the due date is August 15th, for example. This means that the voltage is 8 Volts (since August is the 8th month) and the current is 15 Amps.
Given the voltage and current, find the resistance of the circuit:
Ohm's Law states: V = I × R .
Rearrange the formula to find resistance (R): R = I V .
Substitute the values: R = 15 A 8 V = 15 8 Ohms .
What is the power exhibited in this circuit?
Power (P) is given by the formula: P = I × V .
Substitute the values: P = 8 V × 15 A = 120 Watts .
Thus, for a due date of August 15th, the resistance of the circuit is approximately 0.53 Ohms, and the power is 120 Watts.
For a due date of September 12th, the voltage is 9 Volts and the current is 12 Amps. The resistance of the circuit is approximately 0.75 Ohms, and the power exhibited in the circuit is 108 Watts.
