Question
A **60.5 m** length of insulated copper wire is wound to form a solenoid of radius **2.2 cm**. The copper wire has a radius of **0.51 mm**. (Assume the resistivity of copper is \( \rho = 1.7 \times 10^{-8} \, \Omega \cdot m \).)

**(a)** What is the resistance of the wire?  
\[ \boxed{ \phantom{xxx} } \, \Omega \]

**(b)** Treating each turn of the solenoid as a circle, how many turns can be made with the wire?  
\[ \boxed{ \phantom{xxxxxxxx} } \, \text{turns} \]

**(c)** How long is the resulting solenoid?  
\[ \boxed{ \phantom{xxxxxxxx} } \, m \]

**(d)** What is the self-inductance of the solenoid?  
\[ \boxed{ \phantom{xxxxx} } \, \text{mH} \]

**(e)** If the solenoid is attached to a battery with an emf of **6.0 V** and internal resistance of **350 m\(\Omega\)**, compute the time constant of the circuit.  
\[ \boxed{ \phantom{xxxxx} } \, \text{ms} \]

**(f)** What is the maximum current attained?  
\[ \boxed{ \phantom{xxxxx} } \, A \]

**(g)** How long would it take to reach **99.9%** of its maximum current?  
\[ \boxed{ \phantom{xxxxx} } \, \text{ms} \]

**(h)** What maximum energy is stored in the inductor?  
\[ \boxed{ \phantom{xxxxx} } \, \text{mJ} \]
