Use Ohm’s law to find the resistance of the light bulb if you had a 20 volt battery and 0.57 amps of current. Show your work for
aleksley [76]
For this case we have the following equation:
 V = I * R
 Where,
 V: voltage
 I: current
 R: resistance
 By clearing R we have:
 R = V / I
 Substituting the values:
 R = (20) / (0.57)
 R = 35.09 Ohms
 Answer:
 
The resistance of the light bulb is:
 
R = 35.09 Ohms

How do I solve p(q-2)(r-3)
guajiro [1.7K]
Since you have parentheses, you will first multiply (q-2)*(r-3) which equals (qr+6). So now its simplified to p(qr+6) which equals pqr+p6.
