Not so much an engineering question, but electrical. I've got a noisy phone line in my kitchen and not sure what's going on... more curious about the electrical theory than anything else. -when operating either of 2 light dimmers in the area, loud hum on phone line. -when first touching any grounded appliance, hear a click on the line as if I am discharging or something. -the phone is plastic all around so it seems bizzare to me that it would make any noise when touching appliances. Any thoughts? Thanks.
